    The Unified Numbering System for Metals and Alloys (UNS) is an alloy designation system widely accepted in North America.Each UNS number relates to a specific metal or alloy and defines its specific chemical composition, or in some cases a specific mechanical or physical property.

  6. Accelerator mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Accelerator_mass_spectrometry

    Accelerator mass spectrometry (AMS) is a form of mass spectrometry that accelerates ions to extraordinarily high kinetic energies before mass analysis. The special strength of AMS among the different methods of mass spectrometry is its ability to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. 14 C from 12 C).
